Description

[0002] Ceramic green body drying refers to the process of removing moisture from the green body. The green body strength is improved after drying. This is convenient for transportation, kiln loading and firing. The reduction of moisture can prevent waste caused by large amount of water discharge from the green body when the temperature rises in the initial firing stage.

During the heating process, the moisture in the ceramic blank gradually evaporates and is discharged from the oven. When drying with this method, the burning natural gas flame is located on both sides of the moving ceramic blank, which will cause uneven heating of the ceramic blank, resulting in deformation and cracking of the blank, thus damaging the blank and poor drying effect.
